CVE-2026-11558
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA security vulnerability has been detected in CodeAstro Payroll System 1.0. The impacted element is an unknown function of the file /home_salary.php. The manipulation of the argument rate/salary_rate leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceSQL injection vulnerability in CodeAstro Payroll System 1.0's /home_salary.php file. The rate/salary_rate parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject malicious SQL code.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm CodeAstro Payroll System installationSearch for 'CodeAstro Payroll System' in application files, headers, or documentation. Check the web root for the presence of the /home_salary.php file.Affected if The application is CodeAstro Payroll System and the /home_salary.php file exists in the web directory.
-
Verify the application versionCheck version information in source code comments, README files, or any version tracking within the application.Affected if The installed version is 1.0 or cannot be determined but matches the affected product.
-
Inspect the vulnerable file for the SQL injection patternOpen /home_salary.php and search for direct use of $_POST['rate'] or $_POST['salary_rate'] or $_GET['salary_rate'] in SQL queries without prepared statements, parameter binding, or sanitization functions.Affected if The file contains SQL queries that directly incorporate the rate/salary_rate parameter without parameterized queries or input sanitization.
-
Check if the vulnerable parameter is accessibleDetermine if the /home_salary.php endpoint is accessible via HTTP GET or POST requests. Test by reviewing the application's routing or by attempting a request to the endpoint with the salary_rate parameter.Affected if The endpoint is accessible without authentication or with user-level authentication that can be obtained.
-
Look for similar SQL injection patterns in the applicationSearch the codebase for other files using $_POST or $_GET parameters directly in SQL queries, particularly in salary or employee-related modules.Affected if Additional files contain similar unsafe SQL query patterns with user-supplied input.
A user is affected if they run CodeAstro Payroll System version 1.0 with the /home_salary.php file accessible and the vulnerable SQL query pattern present in that file.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL queries with parameterized queries/prepared statements and implement proper input validation on all user-supplied parameters.
